Application. filec't November t3, i912. Serial To all vi 2 0777, it mayconcern Be it known that ii, ALLEN lliooirrs a citizen of the UnitedStates and resident oi Detroit, l i a vne county State of liiichins.,have inventedcertain new and useful linprovements in Gearing of Whichthe tollowing is a specification.

This invention relates to motor vehicles and particularly to the gearingsnrl driving mechanism thereof.

The invention is particularly arlsptecl for use in commercial vehiclesor trucks, in which considerable reduction in speed is reqiiireclbetween the crank shaft of the motor and the tll'lvlilg wheels, anti inwhich it is tlesirerl to operate an auxiliary mechanism at variousspeeds from one of the operating shsit'ts ot the gear mechanism.

One of the objects of the invention. is the production eta motor vehiclein which there is c constant speerl reclliction between the driven shaftot the gear box and the trans mission or propeller shaft.

Another object of the invention is the prorluction compact drivingmechanism havin the above characte 'stics which the shaft or the ear boxis alinecl or eoaxicllv arranged in relation the transmission shatt.

ifiinother object of the invention is to pro vicle a motor vehiclecaring in which the end. of thealinerl" l n shait oi the gear he may beprovided with a gear or pinion tor the purpose of operating an enxiliaryniecl'ianisin such as e WlHCllaSS. i

U'ther objects of the invention will appear from the followingdescription, taken in connection with the drawings which form a part ofthis specification, anti in which Figure 1 is a sirle elevation of thecentral part of a motor vehicle with parts broken away snii showing t cgear lJOX entl driving mechanism in ertical section; .l ig. 2 is atransverse section 9 E2 2 ct Fig. 7;; 3 is a vertical ction approii ithe line 8-3 or Referring one of the npon wli' pow oi the r":

through the rear wall of the compartment 16, being mounted therein in abearing fl, and its projecting end is provided with a gear 42, which isadapted to mesh with a sliding gear 43, shown in the drawing as being ininoperative position. The operative position of this gear is indicatedin dotted lines at 44.

It will be understood that the gear 43 is adapted to be connectedthrough its shaft 5 with an auxiliary mechanism, such as a Windlass orother device, to be used at intervals on the vehicle, whereby the manualoperation of such device is dispensed with and the motor substituted asthe power for operating), the mechanism. By connecting the gear 43 withthe shaft 21, as shown herein, the mechanism operated by the shaft 4C5may be driven at various speeds through the gearing in the compartment15.

A transmission shaft d6 is also mounted in the compartment 16, and it isshown as in alinement with the lay shaft 22, so that its forward bearingl7 is mounted contiguous to the bearing 38, above referred to. Its rearbearing 48 is mounted in the rear wall of the compartment 16, and ashaft l9 has its forward end mounted in a plain hearing 50 in the shaft46. The shaft 49 extends through the rear wall of the compartment 17,and is mounted in a bearing 51 therein, this shaft forming the propellershaft of the vehicle, and connecting with the driving wheels thereof.Thetransmission shaft 46 is provided with a sprocket 52, somewhat largerthan the sprocket 40, and a chain 53, preferably of the silent type,connects the sprockets 40 and 52, so that the shaft 46 is constantlyconnected withthe shaft :21 and driven thereby at a reduced speed. Therear end of the shaft 46 is formed with clutch teeth 54, and a collar 55sliding on the square portion of the shaft 49 is provided with similarteeth 56, so that the shaft 46 may be clutched to the shaft 49 fordriving the latter direct.

It will be understood that with the vehicle standing, the shaft a9 maybe disconnected from the shaft 46 through the clutch teeth 5456, and thegear 43 may be moved into operative relation with the gear 4?- foroperating the auxiliary mechanism. When it is desired to use the motoragain for driving the vehicle, the gear 43 is moved to inoperativ'eposition and the clutch 5%l-56 again ongaged.

A specific embodiment of the invention has been described in detail,which embodiment is deemed to be new and advantageous, and will bespecifically claimed, but it should be understood that the invention isnot limited to the exact details of construction shown, as it will beapparent that changes may be made without departing from the spirit andscope of the invention.

Having thus described my invention, what I claim and desire to secure byLetters latcut, is:

In a motor vehicle, the combination with the alined driving anddriven shafts, and gearing connecting said shafts to operate the drivenshaft at various speeds relative to the driving shaft, of a transmissionshaft out of line with the driven shaft, driving mechanism constantlyconnecting the driven shaft with said transmission shaft, and a seconddriving connection on said driven shaft.

2. In a motor vehicle, the combination with the alined driving anddriven shafts, and gearing connecting said shafts to operate the drivenshaft at various speeds relative to the driving shaft, of a transmissionshaft out of line with the driven shaft, chain mechanism for driving thetransmission shaft from the driven shaft at a reduced speed, and asecond driving connection on the driven shaft beyond said chainmechanism.

3. In a motor vehicle, the combination with alineddriving and drivenshafts, a lay shaft, and gears on said shafts for driving the drivenshaft at a plurality of different speeds relative to the driving shaft,of a transmission shaft alined with said lay shaft, and speed reducinggearing between the driven shaft and the transmission shaft.
